Description of Arguments
Query
Command or Query.
Group a modulator/demodulator pair into a modem. A grouped mod
and demod will respond to either address, in the form x, where:
0=Both sides ungrouped
1=Left side (as viewed from back of chassis) grouped
2=Right side grouped
3=Both sides grouped
Example: GRP=3 (both sides of chassis are grouped into modems)
Command or Query.
Defines how TA/CA control the HSSI interface, where:
0 = TA to CA loop (default)
1 = RR control CA, TA control Tx output.
Example: HHC=0 (TA to CA loop)
Command only.
Resets internal pointer to allow RNE? Queries to start at the
beginning of the stored events log.
Command or Query.
Sets the IP Address and network prefix for the 10/100 BaseT Ethernet
management port, in the format xxx.xxx.xxx.xxx.yy where:
yy is the network prefix (0 to 31)
Example: 010.006.030.001.24
Command or Query.
Fine adjustment to the internal reference oscillator tuning voltage,
thereby, fine tuning the required internal reference frequency, in the
form sxxxx, where:
s = sign (- or +)
xxxx=Range: -2048 to +2047.
Example: IRA=+0192
